As far as sunscreen protection is concerned, you can easily get overwhelmed with all the information about SPF available. However, you may have overlooked some important information about skin care basics. The most damaging sun rays are the UVC but luckily they get soaked up by the ozone layer which is kind of thin now.
The UVA rays cut through the skin layers deeply are the cause of early aging like age spots and creases. Even though your skin won’t show an indication of sunburn, it still experiences damage. The UVA are also what causes blindness and cataracts. Besides adding to the impact of UVB rays, UVA rays may be responsible for special kinds of skin cancers. UVB sun rays are strong makers of melanoma and basal carcinomas.
The ratings of a sunscreen SPF which means sun protection factor tells the buyer how long they will get protection from the harmful rays but don’t forget this is not related to UVA protection. For an average outdoor person, a sunscreen with an SPF of 15 lets them be outdoors for around 150 minutes before their ski starts burning. This figure isn’t balance since it only gives protection when you compare SPF 30 97 % protection against UV rays with a 93% protection rate for SPF 15.
How do I know what sunscreen to buy? A sunscreen with an SPF of 15 like when you walk back and forth to the car of for accidental exposure is suggested by former president of Revolution Health. On the contrary, if you plan to be outside for along time like or a reunion, playing sports, or a picnic, opt for a sunscreen with SPF 30.
The best skin care for read haired and fair skin people is an SPF of 50 which indicates a 99% guarding factor as stated by the Skin Cancer Federation. This is also good for those who take medication that places them at higher risks of sunburn or those who have a history of melanoma.
Wide Spectrum Protection indicates the products guards against UVA rays. When you buy sunscreen, look on the label for elements like zinc oxide, titanium oxide, and avobenzone. Avobenzone could annoy certain skin types.
When does it expire? Look or the expiration date on the bottle. If you can’t find one, the rule of thumb is to toss them after two or three years. Some skin care professionals disagree with this. A associate professor at Harvard Medical School wrote in an article urging everyone to discard sunscreen after only one year.
You must store your sunscreen the right way so it won’t lose its effectiveness. Keep it sealed tight in a dry cool place.
